In matpats latest ddlc theory him or one of his staff members traced and recolored some orginal art work of yours and did not credit you and he is making money off your work so you can file a copyright claim and get the video taken down I hope this was helpful

Does it matter of the horns are in the wrong spot? Maybe Satchely did not want then on her forehead. Characters are allowed to be drawn in different or slightly off designs, just look at any of the VOCALOID characters. They all have many different slightly off or totally different fanart designs. Not all the details must be exact to the original design.

It's been a second since you last uploaded something, but it was well worth the wait. This looks amazing and is actually pretty interesting to see compared to other Zero Two fanarts that I have happened to have seen. Great job, and good luck with all of your commercial work! Keep up the awesome work!
